Abstract
The invention belongs to the technical field of engines, and particularly relates to a timing cover cap for an automobile engine. The timing cover cap for the automobile engine comprises a cover cap body, wherein the cover cap body integrates a water pump and a crankshaft oil seal at the front end of an engine cylinder body and is an aluminum alloy cast, the thickness of the wall of the cover cap body is 4 mm, and a reinforcing rib is arranged on the lateral surface of the cover cap body. The timing cover cap for the automobile engine resolves the problems that due to the fact that the structural design of an existing timing cover cap of the automobile engine is unreasonable, the wall thickness size of a product is large, the product is heavy, a fastener hole is designed complexly, and the like.
Description
Technical field
The invention belongs to technical field of engines, be specifically related to the motor car engine timing cover.
Background technique
The timing cover of motor car engine plays the seal protection effect to timing system device in motor, and because the timing system device can produce larger noise in engine working process, therefore, timing cover can also play the effect that reduces noise.
Now present, the timing cover of motor car engine adopts the cast iron materials casting mostly, and not only the wall thickness dimension of product is larger, and product is heavier, is assembled to the growth requirement that can't satisfy the automobile light in automobile; And fastener hole when design, need to first cast out step, could use after boring, tapping, greatly reduce working efficiency, increased the cost of production of enterprise, be unfavorable for very much long-run development and the progress of enterprise.
Summary of the invention
Purpose of the present invention: bring for the timing cover structural design that solves existing motor car engine is unreasonable that the product wall thickness dimension is large, product is heavier and the problems such as fastener hole design trouble, and proposition motor car engine timing cover.
Technological scheme of the present invention: motor car engine timing cover, comprise the cover cap body, water pump and the crank shaft oil seal of described cover cap body integrated engine cylinder body front end, described cover cap body is aluminum alloy die casting, the wall thickness of described cover cap body is 4 ㎜, and the side of described cover cap body is provided with stiffening rib.
Motor car engine timing cover of the present invention, because the cover cap body is aluminum alloy die casting, the wall thickness of cover cap body is 4 ㎜, therefore the wall thickness dimension of product is very little, and the weight of product is lighter, is installed to the growth requirement that can satisfy the automobile light on automobile; Because the side of cover cap body is provided with stiffening rib, therefore guaranteed the requirement of strength of product, make product can satisfy usage requirement.
Further, described cover cap body is provided with fastening screw.
Because the cover cap body is provided with fastening screw, therefore fastening screw can straight forming during die casting, need not first to cast out step, then boring and tapping, greatly improved working efficiency, reduced the cost of production of enterprise, be very beneficial for long-run development and the progress of enterprise.
Description of drawings
Fig. 1 is the structural representation that motor car engine of the present invention is used the embodiment of timing cover.
Embodiment
As shown in Figure 1, the invention provides the motor car engine timing cover, comprise cover cap body 1, water pump and the crank shaft oil seal of cover cap body 1 integrated engine cylinder body front end, cover cap body 1 is aluminum alloy die casting, the wall thickness of cover cap body 1 is 4 ㎜, and the side of cover cap body 1 is provided with stiffening rib 2, and cover cap body 1 is provided with fastening screw 3.
In the present embodiment, cover cap body 1 is aluminum alloy die casting, and the material of employing is aluminum alloy, and its density is 2.7g/cm
3, and the density of cast iron is 7.8g/cm
3, like this, the weight of die cast product only have existing casting product weight approximately 34.6%, can satisfy the growth requirement of automobile light.In fact, the product wall thickness of die cast only has 4mm, and the product wall thickness of former casting is 6mm, and this just provides good condition for the design of fastening screw 3.
In addition, the design of stiffening rib 2, consider mainly that the wall thickness of die cast product is thinner, intensity a little less than, and stiffening rib 2 can increase the intensity of product, thereby guarantees that product can satisfy usage requirement.
In addition, manufacturing procedure has been simplified in the design of fastening screw 3 greatly, and during die casting, fastening screw 3 can straight forming, need not first to cast out step, then boring and tapping, has greatly improved working efficiency, has reduced the cost of production of enterprise.
Above-described is only the preferred embodiment of the present invention, should be understood that for a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement, these can not affect effect of the invention process and practical applicability.
